HARRY S. HART, OF CHICAGO, ILLINOIS.

SELECTIVE DUMP CAR.

Application filed April 22, 1924.

7 To all whom it may concern:

Be it known that I, HARRY S. HART, a citizen of the United States, residing at Chicago, in thecounty of Cook, and State of Illlinois, have invented certain new and useful Improvements in Selective Dump (Jars, of which the following is a specification.

The present invention relates to'selective dump cars. i

In railway dump cars, particularly those designed for the carrying of railway ballast, it is highly desirable to be able to dump either outside of the rails upon which the car is mounted or between said rails.

An object of the present invention is to provide a simple and rugged construction of railway dump car adapted for either side or center dumping.

A further object is to provide simple dumping mechanism which will deposit ballast adjacent to'the rails of a railroad track 'with a'minimum oidanger of flooding said rails. v V

A further object is to provide a simple railway dump car of the selective type, in

which dumping may be efiiciently accom- ;plished while the car is traveling at a relatively high rate of speed without danger of flooding the rails.

A further object is to provide a railway dump car capable ol. carrying a relatively large load and having the advantage that dumping may be zu-complished at a rapid rate without danger of rail flooding.

Further objects will appear as the description proceeds.

Figure 1 is a transverse sectional view of a railway dump car embodying the principles of the present invention, certain of the doors of said car being arranged for dumping outside of the tracks upon which the car is mounted; and

Fig'iue 2 is a View taken along the same transverse plane as in Figure 1 but showing the doors arranged for center dumping.

The numeral 1 indicates a center sill, and the numerals 2-2 indicate cross bearers of a railway dump care Said car is provided with the sloping walls 3-3, which extend 1y extending, shalts 13l3.

of the car. Disposed adjacent to the center sill l are the sloping walls -l-4c, which slope dmvmvardly and outwardly from the region of the center sill 1.

Hinged along longitudinal aXes adjacent to the walls 33 are the swinging doors 6--6, which swinging doors when in closed position extend in the same general directions as the corresponding sloping walls 33. Each of said swinging doors 6 is adapted to form a hopper with the corresponding sloping walls 3 and 4;, the two hoppers being arranged longitudinally of the car on the two sides of the center sill. Each of the floors 4% includes a swinging door 7 hinged about the longitudinally extending axis 8. Said doors 7-? are so mounted that when said doors are in open position they will form practically continuous sliding surfaces with doors 6-6, assuming said doors 6-6 to be in closed position; this arrangement being clearly illustrated in Figure 2 of the drawing.

The swinging doors 7-7 are provided with members 9-9 projecting downwardly from the under sides thereof, which members 99 provide attaching means for operating chains l0lO,which maybe controlled in any preferred n'ianner; shafts 11] 1. being illustrated for this purpose. It will be understood that the pulling up upon said chains -40 will move the swinging doors 'T7 to closed position. The swinging doors 6-6 are o icrated by means of chains 12-42, which may be controlled by the longitiulinal- In order to 110] d chains 12-42 in proper positions to exert the necessary turning movement to the doors 6-6, sheaves 1 1-14 may be provided for carrying the operating chains 1212.

Extending downwardly and outwardly fronrthe lower edges of the sloping walls 4-+l, that isfrom. regions adjacent to the longitudinally extending axes 8-8, are the sloping platforms 1515. The lower edges of said platforms 15-15 should be substantially straight and should project to regions late-rally of the rails, for a purpose which will be referred to hereinafter. The edge portions of said platforms 15-15 may be the rails.

braced by any preferred means, as, for example, by the braces 16-l6.

The wheels of the car are illustrated by the numerals 1'i'17, which wheels are adapted to rideupon the rails 18-18. As noted above, one of the objects ofthe vpresent lllVtlIllllOlllS to provide a structure means of which ballast may be efficiently dumped either between the rails 1818 or outside thereof without danger of flooding For this reason the doors 'T-T and the sloping platforms -15 are so designed that ladiug flowing there-from will naturally assume such a position, due to its angle of repose, that "flooding of the rails will-be avoided.

twill be understood, of course, that the angle of repose of the lading will vary slightly with different kinds of lading and with va ying degrees of wetness of said lading, but, speaking generally, the maxi-- mum dimensions of a heap of hiding between the tracks may be defined by the broken lines indicated by the numeral 19 of Figure 2, which indicates the angle of repose of said lading. It will-be noted that, given a predetermined angularity between the lines 1-9, the positions of said-lines will be defined-bythe lower edges of the swinging doors ?7 when said doors arein their full open position, as indicated in Figure-2; i. e, in alignment with their adjacent doors 6-6 when said doors 66 are in closed positions. It will be understood, of course, that there is a slight permissible variation in the base ofthe triangle representing the heap of lading between the rails. Theba-se of said triangle may be atvany level below the tops of the rails, so that said base is bounded by the inner surface of the rails below the topsthereof.

The lines defining the limits-of heaps of lading outside of the rails are indicated by the numerals 20. Given a predetermined angularity of said lines 20 20 relative to a horizontal base, the positions of said lines are defined by the lower edges of the shaving platforms 15-15.

d hen it is desired to deposit hiding-between the rails, the doors 7-? may be opened to permit the passage of lading to the region between said rails. Assuming that the doors 7-4 areswung to positions in alignment with the closed positions of the doors 6-6, the positions of the lines 19 indicating the top of the maximum permissible heap of 'lading will be defined oy the lower edges of doors 7-7. "-By reason of the fact that the doors 77 direct lading to a medial region spaced equally from the rails 9-9, and inasmuch as the.

boundaries of the heap of ladinglare defined by said doors 7?, the net result is that when the car is being moved along the track, at which time flooding'of the rails is most dangerous, the illustrated construction in sures a maximum of safety in this regard.

The sloping platforms 15 15 will define the boundaries of the heaps of lading deposited outside of the rails, the delivery of lading to .said platforms :being controlled bydoors 6-6.

It .will be noted that according to the present invention a dump car is provided which combines the advantages of simplicity of operat on, large carrying capacity, and
